is Claims. (Cl. zas-sain) This invention relates to printing mechanisms for tabulating machines or the like, and is primarily directed to the provision of means for selectively feeding classified record sheets to a print- 5 ing device for receiving data of the same classiflcation.

It has heretofore been proposed to feed a card or.bil1 to a printing device to receive a group of item's and the totals thereof, such data constituting a statement of a particular persons account. Since it is desirable that suchccards be classified in some manner it is essential that only those cards .be fed to the printing device whose classiflcations compare with the classiiications of the data entered. Otherwise, it is apparent that without' the provisionof such a device, entries may be `effected upon the wrong records.

It is then a broad object of the present invention to provide for the selective feeding of a card or bill when the classification of the card or bill is identical with the classification of the items i entered.

It is a further object of the invention to condition the machine when a discrepancy exists, in such a manner that the `operator may be able to discern and rectify the error.

In connection with the above it is a further object to provide an indicating device for visibly invdicating the classication of the items entered whereby the operator may observe the classification of the items entered and if necessary compare the` same ywith the classification of the bill selectively fed to receive such items.

In the present instance the item entering means comprises record cards which are successively fed to the usual analyzing mechanism. The classiflcation is represented by perforations and a similar means of classification is provided for classifying ithe bills. The cards and bills are preferably fed in an inverse relation and it is also an object of the,invention to provide for the comparison of the records and bills when fed in this particular manner.

The present invention in its broadest aspects, may not contain the above feature and its adoption it should be understood, is to meet a particular situation, and withminor changes the comparing mechanism may be adapted to compare cards and bills fed in the saine manner.

To these and other ends the invention consists in the novel features of construction, arrangement of parts, and combination of elements, hereinafter described, and more particularly set forth inthe claims.

'I'he improvements are shown in connection 90 with the tabulator illustrated in the Lake Patent #1,600,413 dated September 21, 1926 to which reference may be had for details of construction of the card feeding, analyzing and total taking devices. Suilicient explanation of these devices will, however, be given to explain their coordination with the present improvements and other ffeatures of the illustrative machine.

Referring particularly to Fig. 14, the tabulator referred to includes a set of upper brushes 20 100 designated as the control brushes and a set of lower or adding brushes 21. The upper brushes analyze the perforations of theV record card 22 (Fig. 2). The vlower brushes 21 also analyze the perforations in the same iield of the record card. The field 24 (Fig. l) of perforations of the record card may comprise classiiication data inv order that a disagreement of classification perforations of successive cards at the upper and lower brushes may cause the machine to go into an automatic total taking operation more fully explained in the Lake patent. In the event of continued agreement of successive cards the machine will continue with the item entering operations controlling printing and adding instrumentalities in accordance with the data representing perforations of other elds.

In the present embodiment the machine is adapted to print the items 25 (Fig. 2) and the totals 26 thereof upon a card designated hereinafter as a bill 27. classification perforations 28 and a printed number 29 which is a translation of the classification perforations and is provided for the convenience of the operator in discerning discrepancies. A new bill is fed as an incident to each total taking operation at which time the first Card of a new group is already at the control brushes 20. Upon the agreement of the classification perforations 24 and 28 the machine will proceed with item entering operations of the new group but any discrepancy between the new bill fed and the first card of a new group will be observed by the operator by stoppage of the machine.

It should also be observed that in the present embodiment the record cards 22 are fed by the card feeding mechanism with the 9 index points leading while in order to get a proper print on the face of the bill, the latter is fed with the 0 perforations leading. The present improvement also provides for the checking of cards and bills when fed to their analyzing brushes in an inverse relation.

The circuit arrangement in connection with the control brushes '20 comprise cam controlled contacts 29a intermediate the line side 30 and brushes 20, the latter being plugged by wires 3l to control magnets 32 which are permanently connected to the other line side 33 by a wire 34. The plug connections are only shown for one order, it being obvious that as many units are plugged as there are columns analyzed. Upon the passage of the first record card of a new group past the control brushes 20 and which is concomitant with the item entering operation of the last card of the last group, impulses will be transmitted to magnets 32 at differential times.

Each magnet when energized attracts its related armature 35 (Fig. 7) to unlatch a stop member 36 which is then urged by a spring 37 to bring a stop portion 38 in engagement with one of a series of notches 39 formed in the periphery of a spider 40. Three spiders 40 are provided for each column and they are driven frictionally by a shaft 41 which is given a third of a revolutionV for each card cycle. The notches 39 pass by the stop portions in synchronism with the index points of the record card 22 fed past the control brushes 20.

When a spider 40 is stopped by an extension 38 the spider will be held back during a portion of the cycle of operation of shaft 4l and then released to permit a supplemental movement. Prior to the end of the cycle the stop member 36 will be relatched to permit the spider to be driven supplementally, this movement occurring during the time the blank portion of the record cards above the 0 index points is being fed past the brushes 20. During the next cycle of operation, which it will be recalled, is a total taking cycle if cards disagree, the spider will be driven by connections from the total taking devices. The holding back of the spider caused by the actuation of stop member 36 is equivalent in units to the numerical value of the index point perforation of The bill 27 also containsy the record card in the particular column analyzed. For example if the units index point was 3 the spider would be held back 3 steps of operation.

For the present it may be considered that each spider 40 is provided with a cam portion 42 adapted to engage a foot 43 of a contact operating lever 44 loosely pivoted upon a rod 45 so that the engagement of the elements 42 and 43 will cause the arm 44 to be rocked to close contacts 46. Since the spider 40 has been held back a number of steps which is equal to the numerical value of the index point of the tabulating card analyzed the' actuation of contacts 46 will be accordingly held up a complementary amount during the total cycle.

Since the particular means utilized to cause the machine to enter into a total taking operation as an incident to change in card groups is different from that shown in the Lake Patent #A1,- 600,413 an explanation of this unit will now be given, but for the more detailed description of this unit, reference may be had to the Carroll Patent No. 1,726,539 ldated September 3, 1929.

Impulses caused by the passage of an upper brush 20 through the card perforation causes energization of a related magnet 47 the latter being plugged to the related brush by a plug connection 48, the group of magnets 47 having a connection to the line side 33 by wire 34. By jumper or plug connections 49 the other magnet 50 of a pair 47-50, see Fig. 9, is serially connected to the related one of the lower brushes 21, one side of the groupY of magnets 50 having a return connection to the line side 30 by a wire 51.

Referring particularly to Fig. 9 each pair of magnets 47-50 is associated with a balanced armature 52 having a wedge-shaped terminall 53 fitting in a similar shaped notch of one arm of a bell crank 54. The armature is held in a neutral position by a spring 55 and is active to keep contacts 56 closed against the normal tension of the upper blade which tends to maintain the contacts 56 open. The pairs of contacts 56 are series connected (Fig. 14) in a circuit 57 and the connections therefrom to the rest of the electrical apparatus is similar to the Lake Patent No. 1,600,- 413 hereinbefore mentioned. It is 'suflicient to state that whenA impulses are transmitted to a pair of magnets-47-50 simultaneously the armature'52 will remain in a neutral position and if this action is the same for all controlling columns, the series of contacts 56 will remain closed and the machine will continue with item entering operations. A dis-simultaneous energization of a pair of magnets 47-50 will, in the manner fully explained in the Carroll Patent No. 1,726,539, cause the related pair of contacts 56 to be opened and since the circuit 57 is now opened a total taking operation will ensue, as fully explained in the patent No. 1,600,413. total taking cycle the contacts 56 are closed in relatched position by a bail member 58 pivoted at 58a and operated by a cam 59. In operation the bail member 58 depresses the upper blade of contacts 56 to close said contacts and far enough so that the upper blade is below the lower end of the vertical arm of the related bell crank 54, whereupon spring 55 is now effective to shift said arm over the upper blade to keep contacts 56 closed as bail member 58 is shifted upwardly l to its normal position.

As an incident to each total taking operation a shaft 60 (Fig. 4) is rotated and through suitable connections a new bill is fed to the bill analyzing brushes. Prior to the explanation of the devices At the end of the position shown in Fig. 10 as shaft 81 is shifted' for effecting the above function they means for driving the spiders` 40 during the item entering operations will first be described.

In the Hollerith tabulator a shaft 61 (Fig. 4) is rotated during each item entering operation. By a. pair of bevel gears 62 a connecting shaft 63 is similarly driven. 'I'he upper end yof the shaft 63 carries a bevel gear 64 in mesh with a bevel gear 65 (see Fig, 12 also) secured to a stub shaft 66. The latter is adapted to drive a shaft 67 by a pair of one-to-one ratio gears 68. Shaft 67 (see Fig. 6) has secured thereto a notched element 69 the notch of which is adapted to be received by the engaging end of a spring urged pawl 70 pivoted to va profile cam 71 (see also Fig. 5). By a connecting sleeve 72 cam y71 is secured to a pinion 73 which is in mesh with a gear 74 secured to the shaft 41. When shaft 67 is driven the notch in disk 69 engaging pawl 70 drives cam\71 and the connected gear 73, the gear ratio being so selected as tofprovide an angular movement of gear 74 and shaft41 of 120 for each card cycle. 'I'he shaft 41 is adapted to receive the series of spiders 40 which are arranged and mounted on the shaft 41 andvurged together by a spring 75 so that they may be frictionally driven by the shaft collectively but each stopped independently at differential times, as before explained.

It is also desirable to be able to know the group number of each card passing the control brushes and to this end each spider has secured to it an irregular shaped cam plate 76 (Fig. 7) ions,

in the plane of a. feeler finger 77 `and which cam plate has the aforementioned cam portion 42. For each order an indicator segment 78 is provided bearing indicia one of which is visible through a sight slot 79a (Fig. 3) to visibly indicate the position of the related indicator segment 78. Each indicator segment is loosely mounted on shaft 45 (Fig. 7) and has a link connection 79 to an integral arm 77a of the feeling finger 77. A series of the latter are pivoted on l a shaft 81 dependingly hung from shaft 45 by a pair of arms (see Fig. 5).

The arms 80 as shown in Fig. 5 are secured to the shaft 45 and the latter has secured thereto an arm 83 carrying a roller (see Fig. 8) engaging a profile cam 84 driven by shaft 67 in/a clockwise direction. As the shaft revolves the cam 84 will rock shaft 45 and by rockingframe 80-81 downwardly from the Fig. 7 position to the Fig. l0 position it will cause the (feeler fingers 77 to be shifted so that one of the feeler fingers is caused to engage a cam edge 85 of the particular element 76 in cooperation therewith and which at this time is stationary in its position of adjustment. As each feeler finger strikes its related cam during a continued downward movement of frame 80-81 caused by rotation of cam 84 it will be rocked about its pivotal point 81 thus elevating the related indicator segment 78 through the medium of link 79. The rocking of la feeler finger continues until frame 80, 81 is in its extreme shifted position determinedby the' cam 84, as shown in Fig. 10. 'I'his position of' adjustment will be held by a pawl 82 pivoted on a xed rod 82a, engaging the appropriate one Aof a series of notches 86. It is understood of course,

that the final positioning of the indicator is dependent upon th'e position at which the cam element 76 is stopped at vthe end of the analyzing cycle and, inl turn, represents the index point anlyzed.

77 and its arm 77a will be rocked clockwise about shaft 81 to the position shown in Fig. 10, thereby` straightening the toggle formed by arm 77a and link 79 thus rocking the indicator segment to the position shown in Fig. 10 so that the numeral 7 is at the reading line.

After the parts have been positioned as shown in Fig. 10 continued rotation off-'cam 84 in a clockwise direction will permit the frame 80, 81 to be restored to the position shown in Fig. 7, the feeler fingers 77 beingwithdrawn from cooperation with the cam elements 76. Since arms 80 will be merely rocked about their pivotal connections to the indicating segments no movement will be imparted to the latter. The indicator segments will remain in their positions of adjustment latched by pawls 82. 'I'he latter are rocked by abail 87 at the beginning of the next card v cycle, the bail being operated by a cam 88 (Fig. 8) secured to drive shaft 67 and when the pawls 82 are rocked sufliciently to withdraw them (from from engagement with the notches 86 the indicator elements will drop to their lowermost positions, as shown in Fig. 7. The pawls however, subsequently reengage said notches to hold the indicator segments in their newly adjusted posi- The pawls hold the indicators after a card has been read and since shaft 67 is driven clockwise only during item entering operations to operate the pawls 82 to release the indicators the indicator reading is held during the total taking operation. v

Since there are three spiders 40v for each col,- umn as shown in Fig. 7 in connection with a single column a corresponding number of stop pawls 36 are provided, each pawl 36 being in the plane of the related spider. Since only a single pawl is effective during one cycle it is desirable to lock the other pawls of the set and .to this end a hollow tube 89 (Figs. 5, 7 and 10) isprovided and Ifor each set of pawls 36 a plurality of slots 90 are provided. When a certain pawl 36 is to be effective its related slot 90 is positioned with respect to the tail 91, of the pawl to allow it to enter (see Fig. 7) when the armature 35 is attracted. At other times the tail 91 of the pawl will ride on the periphery of the tube 89 and is thereby locked against movement. Tube 89 has secured thereto at its end a gear 92 (Figs5 and 6) in mesh with a gear 93 attachedto the gear 74 so that rotation of the tube 89 may be effected as an incident to each card cycle and total cycle aswell.

Restoration of the operated pawls 36 is effected by a bail 94 which extends transversely to `cooperate with the complete'set of pawls 36 (Fig. 5) said bail being operated by a cam 95 (Fig. '8) secured to drive shaft 67 and cooperating with an extension 96 of one arm of the bail member 94. It is, of course, necessary to restore the stopped spider 40 to its proper position in order that it may properly control ythe contacts 46 in a subsequent operation. Extending transversely of the spiders 4() is a bail 97 (Figs. 5 and 7) in which is journalled a rod 98 carrying pawl members 99, each memberiss having a set of three teeth 10o, (see Fig. 5) each of which is in the plane of a shoulder 101 of the cam plate 76 attached to the -related spider 40. Each arm of the bail 97 is 1n more detail, if cam 76 occupies the full line provided with teeth 102 in mesh with the teeth 150 of segment racks 103 secured to a rock shaft 104. One end of shaft 104 has secured to it a depending arm 105 (Figs. 5 and 6) carrying a roller in engagement with the cam 71 hereinbefore referred to.

A downward movement of the bail 97 will cause the teeth 100 to engage the stop shoulders 101 of the stopped spiders 40 to positively restore them to their normal starting positions. This operation of course, occurs several cycles of operation subsequent to the time a spider 40 is stopped by its related pawl 36.

As premised hereinbefore, upon a change in card group the machine is conditioned for a total taking operation, during which operation a new bill 27 is fed and it is determined whether it corresponds with the rst card of the new group. For accomplishing this function the shaft 60, which is driven as an incident to a total taking operation in the tabulator disclosed in the Lake Patent No. 1,600,413 drives a connecting shaft 106 (Fig. 4) by a pair of bevel gears 107. The upper end of shaft 106 carries a bevel gear in mesh with a bevel gear 108 secured to the drive shaft 109.

Shaft 109 has secured thereto a gear 110 (Fig. 6) adapted to drive a gear 111 through an intermediate pinion 112. Tne pairs of feeding rollers 113 and .114 are intergeared and the lower gear of each set meshes with the larger gear 111 so that a driving connection is established between shaft 109 and the feeding rollers 113 and 114.

Feeding of the bills singly from the supply hopper 115 is effected by a picker 116 of the usual form and is reciprocated by a pair of arms 117 secured to a rock shaft 118, the latter having secured thereto an arm 119 carrying a roller engaging the race of a box cam 120 secured to shaft 109. Each revolution of the cam 120 will cause the picker 116 to feed the lowermost bill to the feeding rollers 114 in order that the bill perforation analyzing brushes 121 may analyze the classification perforations of the bill, (see also Fig. 11). The bill is fed from the brushes 121 to a rotatable platen which is'driven concomitantly with the feeding rollers so that the bill is fed around the platen 122 between the periphery thereof and a set of spring urged rollers 123.

Reverting now to the wiring diagram (Fig. 14) it will be observed that brushes 121 are serially connected through cam controlled contacts 124 (see also Fig. 6) to the line side 33 and each brush 121 is serially connected through its related magnet 125 and a pair of contacts 46, hereinbevfore mentioned, the latterbeing connected to the other line side 30 by a wire 126.

By reason of the above connection it will be apparent that if a contact 46 is closed by a spider 40 synchronously with the closure of the circuit at the brush control 121 the related magnet 125 will be energized. It is therefore necessary to close contacts 46 at a point during the succeeding or total taking cycle to determine whether the index point of a column of the first card of a new group coincides with the perforation in a corresponding column of the bill. Due to the inverse relation of feeding the record cards and the bills the contacts 46 are closed at a point in the cycle which is the nines complement of the points in the cycle of the energization of magnet 32, thus making possible a comparison of the bills and record cards.

Means are therefore provided for driving the spiders 40 to obtain a closure of contacts 46 during the total taking cycle and referring to Fig. Gitwill beseenthatsecuredtoahaftlwisa cam 127 engaging a roller 1280, of a bell crank lever 128 connected to segment 129 by a link 130 to effect a reciprocation of the segment by the cam 127. The segment teeth drive a pinion 131 loose on shaft 41 and secured to the pinion is a disk 132 carrying a pawl 133 in engagement with a notched disk 134 secured to shaft 41. The throw of the segment 129 is such that engagement of the pawl 133 with one of the notches in disk 134 is adapted to effect an angular movement of 240 of shaft 41. It should also be observed that the functions effected by shaft 67, such as release of pawls 82, reciprocation of feeling fingers 77, and operation of bail 94 are not effected during a total taking operation. However, cam 71 is operated during total taking operations to restore the stopped spiders for readiness during the next item entering operation.

If, as before stated, a magnet 125 is energized by reason of a similarity in the card and bill perforations, the armature 135 (Fig. 6) thereof will be attracted to effect closure of contacts 136. each set of contacts being individually latched by pawls 137. As is best shown in Fig. 6 a vertical arm 135a of each armature 135 has provided at its upper end a notch 135D which is normally engaged by the end of the related pawl 137, the resiliency of the right hand contact blade of contacts 136 maintaining this relationship. When a magnet 125 is energized the vertical arm l35a will be shifted to the left as viewed in Fig. 6 to close contacts 136, thereupon the related pawl 137 will be urged by its spring 136a to engage the portion of the arm 13511 which is above the notch 135i) to thereby hold contacts 136 in closed position. Contacts 136 are series connected and if at the termination of the operation of comparing a bill with a record card, all the contacts 136 are latched closed, a circuit 138 (Fig. 14) will be closed. This circuit is in the automatic starting circuit fully explained in the Lake Patent No. 1,600,413 and when closed permits the machine to go into a tabulating operation in connection with the new group of cards. In the event that the perforations in a particular card column do not coincide the circuit 138 will be opened and the machine will stop, allowing the operator to visibly compare the bill with the record card to correct the discrepancy. This comparison is readily effected since the operator may read the classication number 29 of the bill (Fig. 2) and compare it with the classification number of the record card as eX- hibited by the indicators 78 and which is retained during a total taking operation.

Contacts 136 are unlatched during the first tabulating cycle by a bail 139 secured to a shaft 140 (Figs. 4 and 6) to which is secured a lever 141 actuated by a pin 142 (see Fig. 12).

The machine also includes several groups of printing bars 143 (Figs. 3, 4 and 6) adapted to be struck by hammers 144 to effect printing of items 25 (Fig. 2) or the totals 26 thereof upon the bill 27 in the manner fully explained in the Lake Patent No. 1,600,413.

Certain other adjuncts related to the printing ydevices are also employed among which is a feeding device adapted to give a head spacing to the bill to accommodate the usual printed heading and to determine where the rst item may be printed. In the present embodiment this comprises a cam 145 (Fig. 4) secured to the total shaft 109 and which rocks a bell crank lever connection 146, one arm of which is connected to a link 147, the latter being adjustably mounted on the arm by a device. such as that illustrated by numeral 148. The link 147 is articulated to a drive segment 149 in mesh with a gear 1505 adapted to drive the platen 122 by a train of gears 150, 151 through a pawl and ratchet device 151a (Fig. 12). This driving connection is effective to rotate the platen a predetermined amount to effect the desired initial spacing `of the bill.

For the purpose of effectively stopping the rapid rotation vof the platen when the desired amount of bill feed has been accomplished, the detent device such as that illustrated in Figs. 12 and 13 is preferably employed. In cooperation with a ratchet wheel 152 rotatable with the platen is a detent or pawl 153 impositively held by a spring 154 to engage the interdental spaces of the ratchet wheel. The detent mechanism is normally in the .position shown in Fig. 13 and impositively holds the platen duringprinting time but the pawl is' held out of engagement with the ratchet wheel during the time the bill is ejected by mechanism to be described hereinafter and also during the time the platen is rotated for head-spacing the bill. To this end there is secured to shaft 109 a cam 155 having a low portion 156 and high portions 157.

During sheet ejecting and platen rotating time the high portions 157 act upon a rod 158 through bell crank lever 161 and force the pawl 153 downwardly against spring 154 and by means of 'a cam-l ming s1ot'159 and guide pin 160 the pawl 153 is shifted away from the ratchet wheel 152. At the f termination of the above operation the low portion 156 of cam 155 permits the spring 154 to urge the pawl to reengage with the ratchet wheel to prevent overthrow of the platen roller and impositively position the platen. The detent mechanism, however, is effective at a line spacing operation permitting one or more stepsfof rotation'of the roller and held in such position by the interdental spaces of the ratchet wheel. The linespacing devices for spacing the imprints form no part of the invention and any suitable form may be employed. As herein provided for, the Lake machine comprises a rock shaft 162 (Fig. 4) to which is secured an arm 163 connected by a link 164 to a lever 165. A lever 166 secured to the pivotal supporting shaft of lever 165 has a link connection 167 to a pawl-carrying disk 168 which through a pawl and ratchet device 169 (Fig. 12) turns gear 150 to rotate the platen to space the items and totals.

Additional mechanism is also provided `to eject a printed bill as an incident to each total taking bin between rollers 17o and 171 when the frame 172 is rocked to cause the rollers to grip the bill i therebetween. The frame 172 has pivoted there-Y to a link 174 connected to a lever 175 which is rocked by a box cam 176 (Fig. 6) secured to the shaft 109 and is effective to couple the rollers 170 and 171 together to frictionally feed a bill from the platen after which the bill is guided by a plate 177 (Fig. 4) to fall in a receptacle 178.

V The gear 173 rotatable with rollers 170 is driven by a train of gears 174', 175', the latter meshing with the gear secured to the upper feeding roller In the event that the bill does not properly v check with the first record card of a new-group the proper one can be inserted in the hopper and the machine run through a regular reset or total cycle. This will cause the improper billto be ejected and Q1 'woords inversely with respect to each other as the lproper bill fed to the platen. To carry out the above the regular reset key 180 (Fig. 14) is depressed causing the machine to function in the manner described in the Lake Patent No. 1,600,413.

If the bill is in the proper sequence and the record card or cards of a group be in error, the latter may be run out of the machine by the provision of the usual listing or starting key fully shown and described in the Lake Patent No. 1,600,413. Since it is desirable not to have -the items or total of such a group printed on the bill, certain other expedients are also employed. To this -end there is provided a .clutch device 181 (Fig. 4) which disables the connection between bevel gears 107 to prevent the feeding of a bill to the platen at the end of the improper record card `or groups of cards. The printing of items or linvention as applied to a single modification it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.

5. In a machine of the class described, analyzing mechanism for `analyzing designations on a pair indicated by their relative index points, and means controlled by said analyzing mechanism for comparing the designations to signify the agreement or disagreement in designations of the pair of records analyzed.

6. In a machine of the class described, means for analyzing and comparing designations of a pair of records inversely with respect to each other as indicated .by their relative index points, and means controlled by said analyzing means for comparing the designations for controlling machine operation in accordance with the agreement or disagreement of the designations of the pair of records analyzed.

'7. In a machine of the class described, means for analyzing a designation of a record, means for setting up an element to represent a complement of such designations, and means for analyzing a designation of another record whose index points are analyzed in an inverse relation with respect to the index points of the first named record concurrently with the reading out of the setting of the element.

8. In a record controlled machine, means for analyzing classification designations and item representing designations of tabulating cards fed in successive groups, means for analyzing classification designations of a record constituting a bill, means for representing upon the bill items represented by` a group of tabulating cards, means under control of the classification designation analyzing means of the card and bill for compar; ing the classiiication designations of one of the tabulating cards of one of the groups with the bill to control the representing of the items on the bill if they agree, and means for printing a total of the items upon the bill when the classification of tabulating cards changes.

9. In a record controlled machine, means for analyzing item representing designations of tabulating cards fed in successive groups, means for analyzing and comparing classification designations of one of the cards of a group with the classification designations of one of a group of individual records constituting a bill, means for automatically feeding a bill for each group of tabulating cards, means for printing the items upon the bill dependent upon the determination of the analyzing and comparing means, and means including accumulating means for printing a total upon the bill receiving the items when classification designations of tabulating cards change and for causing automatic operation of the feeding means.

10. In a record controlled machine, a series of records having classification designations, means controlled by a series of tabulating cards having classification designations for printing a series of items and a total upon one of said records, means for analyzing and comparing the classification designations of one of the tabulating cards and one of said records, and means whereby the last named means causes the printing of items and a total when the records analyzed bears the same classification designations as one of the controlling tabulating cards.

11. In a machine of the class described, means under control of a series of tabulating cards having classification designations for printing items indicated on said cards upon one of a series of records having classification designations, means for analyzing the classification designations of successive tabulating cards to effect the continuity of item printing operations while the designations agree, means controlled by said analyzing means for controlling the printing of a total upon the record printed with said items when designations of successive cards disagree, means for presenting another of said records, and means for analyzing the classification designations of the record presented to compare them with the designations analyzed by the tabulating card analyzing means.

l2. In a'record controlled machine, means for entering 'a series of classified items and a related total upon a record, means for comparing the classication of the items with the classification of the record represented by designations on the record to determine the printing of items, and means whereby the total is printed upon the record when successive item entering means are unlike in classincation.

13. In a record controlled machine, means for entering a series of classified items upon a record classified by designations thereon, means for printing a related total upon the record when successive entering means are unlike. means for analyzing the classification designation of the record and upon agreement with the classification of items cause item entering upon the record, and means dependent upon unlike classification of successive items for presenting another record for receiving items all of the same classification but different from the items entered upon the preceding record.

14. In a machine of the class described, the combination with means for entering items of the same classification upon one of a series of records having classification designations, of means for analyzing the designations of one of the records for comparing the classification represented thereby with the classification of the tems to be entered and to cause item printing if classification agrees, and means to cause the printing of a total upon the record receiving the items and automatically cause during the total printing cycle the feeding of a succeeding record to the analyzing means to compare the classification designations of the succeeding record with the classification of items to be subsequently entered. 120

15,. In a machine of the class described, the combination with a series of classified records, of means for printing items of the same class and a related total upon one of the records similarly classified, means for analyzing classification des- 125 ignations of one of the records to determine the printing of items and a total thereon, and means effective upon printing a total upon one of thel records for positioning a successive record for subsequent printing operations thereon.

16.
